Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.Following example are only used for this is clearly described
The technical scheme of utility model, and protection domain of the present utility model can not be limited with this.
As depicted in figs. 1 and 2, a kind of villa elevator instantaneous safety that this utility model provides, including caliper 1,
Offering the passage passed through for cage guide on caliper 1, it is characterized in that, the sectional area of described passage is up-narrow and down-wide isosceles ladder
Shape, the both sides of passage are provided with two identical mutually symmetrical arrestment mechanisms of structure, and described arrestment mechanism includes braked wheel 2, braking
Plate 3 and limiting plate 4, the structure of right side brake mechanism is as in figure 2 it is shown, braked wheel 2 is placed at the hypotenuse of passage, and limiting plate 4 is solid
Being scheduled on the hypotenuse side of caliper 1 upper channel and have gap between limiting plate 4 and caliper 1, keep plate 3 is laterally located in gap, braking
One end of plate 3 connects braked wheel 2, and the middle-end of keep plate 3 connects speed limit rope 5, and the other end of keep plate 3 is provided with connection post 3-1, limit
Position plate 4 is provided with through waist hole 4-1, connects post 3-1 and through waist hole 4-1 and can move in the 4-1 of waist hole.
The duty of this utility model safety tongs is divided into running status and on-position two kinds.When safety tongs is in operation
During the normal operating condition of the i.e. elevator of state, limiter of speed is failure to actuate, and speed limit rope 5 does not produce upwards pulling force, and both sides keep plate 3 is positioned at
Lower section, connects post 3-1 and is positioned at the lower end of waist hole 4-1, and both sides braked wheel 2 is positioned at the position that passage is relatively low near oblique waist side,
Make to leave enough spaces in the middle of in isosceles trapezoid passage to pass through to the guide rail of elevator, and stay between braked wheel 2 and cage guide
There is gap.When the speed of elevator exceedes the maximal rate that limiter of speed allows, limiter of speed sends action, and clamping speed limit rope 5 produces
Pulling force upwards, speed limit rope 5 drives both sides keep plate 3 rapidly moving upward so that both sides braked wheel 2 is rapid along the hypotenuse of passage
Move up, reduce with the gap of cage guide until contacting with cage guide and rubbing action occurring, by lift car stop
On guide rail, to protect the safety of elevator；Safety tongs is made up of two identical brake structures, is distributed symmetrically and is arranged at elevator and leads
The both sides of rail, the braked wheel 2 elevator brake guide rail uniform force made, it is to avoid guide rail deforms；And move past on keep plate
Cheng Zhong, connects post 3-1 and moves up along waist hole 4-1, also by the thrust in passage during can making to move on braked wheel 2, increases
Add the pressure between braked wheel 2 and cage guide, and then increase the frictional force between braked wheel 2 and cage guide, improve braking
Power, limit connection post 3-1 moves up and down scope simultaneously so that during braking, keep plate 3 is without departing from safety tongs body.
As preferred embodiment of the present utility model, the axis of waist hole 4-1 is parallel with the hypotenuse of same wing passage.Further
, the gradient of the axis of waist hole 4-1, more than the gradient of the hypotenuse with wing passage, is also subject to during can making to move on braked wheel 2
To the thrust in passage, increase the frictional force between braked wheel 2 and cage guide, improve braking effect further.
Further, limiting plate 4 is additionally provided with packing ring with the junction of caliper 1, and the thickness of packing ring is more than the thickness of keep plate,
Thus ensure that the keep plate 3 being arranged between limiting plate 4 and caliper 1 can move flexibly.Packing ring is stressed member, in this enforcement
In example, the material selection rustless steel of packing ring.
Further, limiting plate 4 is fixed with caliper 1 by bolt, and gasket sleeve is located on bolt.Bolt make limiting plate 4,
Packing ring gets up with caliper 1 compact siro spinning technology, plays positioning action, and keep plate 3 is flexibly connected with limiting plate 4 by connecting post 3-1,
Under the effect of bolt, whole safety tongs is connected as an entirety.
Further, the outer surface of braked wheel 2 is provided with waveform annular knurl, improves the coefficient of friction of braked wheel 2, improves system
Dynamic effect.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and deformation, these change
Enter and deform and also should be regarded as protection domain of the present utility model.
